<7. Read me files go in :runtime:readme:vendorname folder>

I put my readme files in a CDI Readme subfolder of the PoserReadme's folder. The PoserReadme's folder has been there forever, perhaps started by DAZ/Zygote. I just prefer to utilize it rather than starting a new Readme folder in the Runtime folder.

<9. Texture files should go in the texture folder>

They should go in the textures folder. I've seen them put in a Texture folder which creates a new folder rather than the textures folder created by Poser.

<10. Pose files should place the figure on the "ground">

I personally prefer the hip be zeroed rather than the figure be on the ground, but that is just me.

I prefer merchants not include png files at all unless they are developing only for Pro Pack and P5 as these versions of Poser will generate pngs from the rsrs.

I prefer merchants not force their library folders to the top with !, ~, etc. I don't mind the use of these characters within the merchants folder to help push the most used files to the top.

Just my opinions. Of course, everyone has one, so it is unlikely everyone would adopt a standard. However, it would certainly be good for reference. :)
